Some people believe religiously in smooth laminar flow of fluid past an object to cool that object. But turbulence actually acts to scrub away the boundary layer of air (or other fluid) that surrounds the object to make closer contact between the object and the passing fluid. It is the...

My system is a year-and-a-half-old Dell Dimension 8400 running WinXP, with a Dell wireless keyboard and mouse, and is left on 24 hours a day. Unfortunately the mouse, which requires two AA batteries, uses up batteries very fast, so I'd like to replace the mouse with a more efficient one (but keep...

I'm planning to add some memory to a PC. The motherboard supports "DDR up to 333 MHz (enhanced) memory bus." 333 MHz (PC2700) or slower DDR SDRAM isn't easy to find on today's market, and when you do find it, it's considerably more expensive than the DDR which runs at 400 MHz (PC3200). What...

My local "mom and pop" store has made the following bid for a new system I'm considering. I'd like some opinions about what you think. I'd like to buy local if possible. Expected use is web surfing, email, limited dvd making someday. System will replace a 3 year old P-3 running Win98SE. Intel...

I notice there is always a great disparity between stated hard drive capacity and actual usable capacity after formatting. Is there a chart or other paper anywhere showing maybe comparisons of this between drives, and maybe an explanation of why and how it happens? Thanks Jethro

Hi, As I understand it, most ATX style PC setups have a fan above the CPU that blows air down onto the CPU to keep it cool, and the hot air bounces around inside the PC case until it can find an exit (if it's lucky). As I see it, there are two problems with this, a) unless you have a vent in...

I see good things about PCPC, they have an excellent resellerratings.com rating. A friend referred me to their site. Anyone have hands on experience with this unit? So far haven't found a reveiw about it. From what I understand, a lot of their units are...

Wouldn't you know it! I have a HP 950 PSC AllInOne (Print/Scan/Fax) that I want to install on a new machine with WXP SP2. I can't find the CD that came with it. I've looked & looked. I tried DriverGuide.com, but all they seem to have are print-drivers for this printer under the various OS's.

Hi, I have an old PC which I've just turned into a music machine and (living room) web access. It runs Win 2000 Pro (just) but everything is very slow to load and I mean SLOW. The reason is it has just 64MB RAM, but virtual memory is using about 200MB, plainly I need a RAM upgrade. The...

Hi, I'm experiencing problems with Intel Core 2 E6800 temperatures on my ASUS mainboard, but part of the problem is I don't even know if the values I'm seeing reported on screen are correct or not! I've created a quick web page with a screen shot and details...

Consider this excerpt from the Intel D845HV/WN product guide: | The boards supports system memory as defined below: | | • Up to three 168-pin SDRAM Dual Inline Memory Modules | (DIMMs) with gold-plated contacts | | • PC133 SDRAM only | | • 64 Mbit, 128 Mbit, and 256 Mbit technologies for the

This follows on from my post describing a boot up failure, as the subject heading of that is now misleading. The consistent state now is that my Athlon XP 1800 PC takes about half an hour to boot! And then every operation is similarly glacial. For example, after double clicking My Computer it...

Hi, I find my PCs (no matter PII, P4) produce big noise after power up and most of the noise being produced by CPU fan. I haven't tried overclocking in any of these PCs and I even open the case to improve ventilation but with no improvement. I would like to know how can I reduce that noise due to...

As Rod Speed has pointed out, the clone drive resulting from a cloning of a WinXP system HD should be the only drive with an a WinXP OS on an active partition when booting it up for the 1st time. (Thereafter it can "see" and be "seen" by another OS in the PC.) The hassle is that you have to open...
